Forces and elasticity



When two or more forces are applied to an object, its shape can change; this video looks at the physics and (mathematics) which describe how this can happen.  It also includes material which is relevant to one of the core practical activities for this part of the course which is on investigating the relationship between the force applied to a spring and its extension.
